TALE: A Temporal Active Language and Execution Model

Complex applications in domains such as decision support systems and real time systems require a functionality that is achieved by combining the active and temporal database technologies. In this paper we present TALE, a Temporal Active Language and Execution model. TALE is a temporal active database programming language, combined with an execution model that enables a correct and eecient processing of operations. As such, TALE is a step in accommodating software engineering challenges in modern information systems. TALE primitives are presented using examples and an EBNF. The run-time control mechanism of the model is introduced and TALE properties, namely active and temporal capabilities, and reeective programming capabilities are discussed.
